I should note I've brought this up before. Crossposting to the Gnus
mailing list as well. Concretely, the proposal is to support only Emacs
24.x in Gnus. If XEmacs or Emacs 23 support breaks, then users can
submit patches but it won't be a primary focus for the developers.

Agreed.  Emacs 23.1 is from 2009 so it's similarly outdated though not
as humorous.
